US Patent:

40792315, Mar 14, 1978

Filed:

Mar 30, 1976

Appl. No.:

5/672076

Inventors:

Tibor E. Toth - Florence SC

Assignee:

Union Carbide Corporation - New York NY

International Classification:

B23K 910

US Classification:

21913032

Abstract:

A touchwork system for use in conjunction with a MIG arc welding apparatus comprising a sensing circuit operating at very low output voltages, e. g. 6-8 volts, which senses the touch of the consumable wire electrode to the workpiece when the welding process is started. A control circuit energizes the welding contactor in response to a signal from the sensing circuit and turns on the power supply. At the same time, the control circuit starts the wire feeder motor and also the flow of shielding gas to the torch. A detector circuit detects the flow of welding current and feeds a signal to the control circuit to keep the welding contactor energized and the power supply in circuit and also to maintain operation of the wire feeder motor and the flow of shielding gas to the torch.

Appl. No.:

8/574973

Inventors:

Tibor E. Toth - Florence SC

Assignee:

The ESAB Group, Inc. - Florence SC

International Classification:

B23K 9095

US Classification:

21913021

Abstract:

An apparatus and method for detecting phase loss in a cutting or welding system is provided. The apparatus preferably includes a cutting or welding torch and a power source operatively connected to the torch. The power source for a cutting or welding system preferably has a power circuit which includes an electrical input line positioned to receive power from an external power supply, a transformer having a primary side connected to the input line and a secondary side, a rectifier operatively connected to the secondary side of the transformer, and an output line connected to the rectifier. The power source also has a phase loss detector operatively connected to the secondary side of the transformer for detecting phase loss responsive to a ripple voltage exceeding a predetermined threshold. The method of detecting phase loss in a cutting or welding system preferably includes filtering an electrical signal representative of a voltage so that only a ripple voltage passes therethrough, detecting a change in the ripple voltage representative of a phase loss, and communicating the change in ripple voltage representative of a phase loss to an operator of the system.

Appl. No.:

6/098065

Inventors:

Tibor E. Toth - Florence SC

Assignee:

Union Carbide Corporation - New York NY

International Classification:

B23K 912

US Classification:

21913771

Abstract:

Electric welding system having a governor control for regulating the speed of the electrode drive motor and for controlling the direction of motor rotation in response to voltage and current welding parameters such that during welding the motor is driven in a forward direction toward the workpiece and under the control of a weld speed potentiometer whereas during a short circuit condition and at termination of the welding operation the motor direction is reversed.

Assignee:

The ESAB Group, Inc. - Florence SC

International Classification:

B23K 9095

US Classification:

21913001

Abstract:

An apparatus and method for displaying data to a user of a cutting or welding system is provided. The apparatus preferably has an arc torch including at least an electrode having an arc discharge end and means for creating an electrical arc extending from the electrode to a workpiece and a cutting or welding power source operatively connected to the arc torch for supplying power to the arc torch. The cutting or welding power source preferably includes a power circuit having an electrical input line positioned to receive power from an external power supply, a transformer having a primary side connected to the input line and a secondary side, a rectifier connected to the secondary side of the transformer, and an output line connected to the rectifier. The power source also has a sensor connected to the secondary side of the transformer for sensing an electrical signal representative of at least either a voltage level or a current level, a digital display positioned to display digital data to a user of a cutting or welding system, and a display controller operatively connected to the sensor and the digital display for controlling the digital display responsive to the sensor. The display controller preferably includes a sampler responsive to the sensor for sampling a predetermined number of electrical signals representative of voltage and current and an averager responsive to the sampler for averaging the predetermined number of samples.

International Classification:

B23K 910

US Classification:

21913021

Abstract:

A method and control circuit for terminating a consumable electrode electric arc welding operation which comprises monitoring the welding parameters of the wire drive motor speed and the arc working voltage, comparing the monitored levels with a multiple number of present combinations of both arc working voltage and motor speed with at least one preset combination defining a high arc working voltage representing a long arc condition and with the last preset combination including a motor speed of relatively close to zero; evaluating each preset combination in tandum to determine if the conditions of a preset combination are satisfied and interrupting the power supplied to the arc in response to the satisfied combination of preset conditions.

Assignee:

Union Carbide Corporation - New York NY

International Classification:

B23K 2500

US Classification:

219126

Abstract:

An improved vertical electroslag welding system wherein the driving motor which propels the molding shoes is controlled by varying its speed in response to electrode current thereby assuring a molten puddle which for any set speed will not rise over the cavity wall or become too fluid. The motor is remotely controlled so that the welding current is not directly coupled to the control circuit.
